Aims: To study the constraints faced by pulse farmers in adopting improved pulse production practices and their suggestions to overcome the constraints.

Study Design: Ex post facto survey research design with proportionate random sampling techniques.

Place and Duration of the Study: Nayagarh district of Odisha during 2019-2020.

Methodology: A total of 256 respondents covering 8 villages from 4 blocks of Nayagarh district were selected as sample respondents. The data were collected by personal interview using a well structured questionnaire. The data were tabulated and analyzed by using Garrett’s ranking technique for the study of constraints and suggestions.

Results: The findings of the study indicate that major constraints for adopting pulse production technologies were improper knowledge about recommended doses of pesticides and fertilizers (59.57 percent), lack of knowledge about improved agricultural technologies time to time (59.2 percent), lack of technology and training to create local storage structures (66.55 percent) and inadequate training of farmers (55.49 percent). Major suggestions of pulse farmers to overcome these constraints were improved varieties should be provided (68.04 percent), more number of FLDs should be given in village to enable other farmers to take advantage (66.85 percent) and training be imparted to implement new technologies (66.85 percent).

Conclusion: Research on modification of agronomic practices and their different components for excelling production under changing climatic scenario need to be strengthened with more training for the farmers to enrich their knowledge and skill about pulse production.

India is the major producer and consumer of sugar in the world. Molasses based distillery along with their product (alcohol) generate wastewater called as spent wash. It is acidic nature characterized by high BOD, COD value. The Value Added Product from sugar industry is generated by incineration of spent wash results in ash powder which is found to be rich in potassium. Consequently, a study was conducted to compare the effect of applying Value Added Product (VAP) as a potassic source on maize hybrid COHM(8) with that grown on Muriate of Potash (MOP) as a fertilizer source using a Randomized Complete Block Design with three replications. The treatments include absolute control (T1), 50% STCR (Soil Test Based Crop recommendation) -K through VAP (T2), 75% STCR-K through VAP (T3), 100% STCR-K through VAP (T4), 125% STCR-K through VAP (T5), 50% STCR-K through VAP + 50% STCR-K through inorganic fertilizers (T6) (MOP) and 100% STCR-K through inorganic fertilizer (MOP) (T7). The results showed that, 125% STCR-K as VAP produced better growth and yield characteristic, it was similar with 100 percent STCR-K as VAP and followed by 75 percent STCR-K as VAP when compared to control (T1). It is concluded that application of VAP from distillery spent wash (DSW) can be used as a substitute for inorganic potash fertilizer in maize crop cultivation to get higher yield and sustain soil health.

Solanum lycopersicum L. (Tomato) is one of the plants commonly grown for its edible fruits all over the world. It is an important component of the average Nigerian meal. The present study aimed at investigating the effects of salinity and arbuscular mycorrhizal fungi interactions on morphology of 10 varieties of Solanum lycopersicum L. Ten different varieties of tomato were exposed to three different treatments, salt and arbuscular mycorrhizal fungi treatment, arbuscular mycorrhizal fungi treatment and sterile soil treatment which served as the control. All data collected were subjected to Analysis of Variance (One way-ANOVA).The results of this study showed that effects of the interactions of salinity and arbuscular mycorrhizal fungi (AMF) differs across varieties of tomatoes with significant differences occurring in some varieties; low or no effect in others across other varieties when comparing growth parameters at p<0.05.Tomato plants grown in salt + arbuscular mycorrhizal fungi had the highest plant height, leaf area, stem diameter, number of leaves, number of flowers and highest fresh weight of fruits across most of the varieties compared to other treatments. However, tomatoes subjected to only AMF treatment had the least performance across all the varieties. Thus, from the results of this study, it could be concluded that arbuscular mycorrhizal fungi has the potential to improve tomato plants tolerance to salinity.
